While the looming fiscal cliff dominates political conversation in Washington, some Republicans and business groups see signs of a "regulatory cliff" they say could be just as damaging to the economy. For months, federal agencies and the White House have sidetracked dozens of major regulations that cover everything from power plant pollution to workplace safety to implementation of a landmark law cracking down on Wall Street. In recent weeks, the Environmental Protection Agency has proposed rules to scale back mercury emission limits for new power plants and deal with runoff from logging roads. The National Highway Traffic Safety Administration, meanwhile, has proposed long-delayed regulations requiring auto makers to include event data recorders _ better known as "black boxes" _ in all new cars and light trucks beginning in 2014. Data collected by the recorders is increasingly showing up in lawsuits, criminal cases and high-profile accidents. Massachusetts Lt. Gov. Timothy Murray initially said he wasn't speeding and that he was wearing his seatbelt when he crashed a government-owned car last year. But the Ford Crown Victoria's data recorder told a different story: It showed the car was traveling over 100 mph and Murray wasn't belted in. (AP Photo/The Telegram & Gazette, Tom Rettig, File)
